Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of trapeziometacarpal osteoarthritis. We modified the LRTI, using the palmaris longus (PL) tendon instead of the FCR tendon. The aim of this retrospective study was to evaluate the clinical outcomes of trapeziectomy with our modified LRTI procedure at a mean follow-up of 5 years. ⋯ The modified LRTI procedure provided significant subjective and objective improvements without severe complications particularly related to the harvesting of the PL tendon. This procedure is a valuable surgical option for trapeziometacarpal osteoarthritis and could be a useful salvage modality if the FCR tendon ruptures during the conventional LRTI procedure.
